IPC: H04B3/48
Filed: 1954-03-31
Abstract: 749,297. Inductors; automatic phase control. STANDARD TELEPHONES & CABLES, Ltd. March 31, 1954, No. 9434/54. Classes 38 (2) and 38 (4). [Also in Group XXXVI] In apparatus for measuring the group delay distortion of an electrical communication system over a cyclically swept band of frequencies (see Group XXXVI) the limited and demodulated 100 kc/s. output test signal is applied over transformer 29 (Fig. 2) to a tuned double diode phase detector 13, producing zero output for quadrature between the input and a 100 kc/s. stabilized reference signal supplied over transformer 25 from output transformer 63 of oscillator 15 which comprises an amplifier 61 energizing over transformer 63 one diagonal of a feedback bridge 66 whose remaining diagonal is connected over transformer 62 to the amplifier input. The bridge comprises opposite resistance arms 67, 68, and a variable resistance or thermistor arm 69 opposed by an arm comprising in series a 100 kc/s. piezoelectric crystal 70, a variable capacitor 71, and a variable inductor 72 having a ring core 75 (Figs. 3, 4) reduced in section at one point to comprise narrow parallel necks 76, 77 separated by aperture 78 wound with respective solenoids which are series connected to form the inductance winding 72, in such manner that the fluxes in the necks due to the winding currents are in opposite directions to comprise a closed magnetic circuit. The control winding 59 is toroidally wound over the whole core circumference to produce a flux in the same direction in each neck superimposed on a local polarizing field from adjustable permanent magnet 73 (or a bias field winding) so that core permeability and thus the inductance of 72 is variable in magnitude and sign with variations of control current, without the introduction of spurious E.M.F.'s into winding 72. Control winding 59 is energized over D.C. instrument 74 by push-pull pentode amplifiers 45, 46 responsive to the phase detector output across potentiometer 40, integrated by resistances 47, 48 and capacitances 52, 53 having a time constant of, e.g., 1 second or 50 sweep cycles. Initially, capacitance 71 is adjusted to zeroize the control current measured in instrument 74, after which the reference signal is automatically controlled to maintain quadrature with the average phase of the recovered 100 kc/s. test signals, by variations of inductance 72. Specification 510,379, [Group XL], is referred to.

Title: Improvements relating to capacity measuring devices
Inventor: FIELDEN JOHN ERNEST
IPC: G01R27/02
Filed: 1952-04-21
Abstract: 744,754. Capacity measurement. FIELDEN ELECTRONICS, Ltd., [formerly FIELDEN (ELECTRONICS), Ltd.]. April 24, 1953 [April 21, 1952], No. 9927/52. Class 37. In a capacity measuring device comprising a capacity sensitive bridge including other reactance elements, one of which is varied by a reversible motor energized at low frequency, a high-frequency oscillator supplies the bridge and the unbalance voltage is fed to a circuit which converts it to a lowfrequency current, dependent in phase on the sense of unbalance, which is applied to the reversible motor to balance the bridge and to drive indicating or recording means. The push-pull oscillator 20 operating on positive half-cycles of the H.T. voltage feeds a bridge network comprising capacitors 11, 12 and 15, the variable 16 and the unknown capacitor 13, through transformers 27 and 29, the centre-tapped secondary 9, 10 of the latter forming the other two arms of the bridge. The voltage between this tap and an earthed tapping between the capacitive arms is applied to the tuned circuit 19, 30 and is then amplified in the amplifier 31 which has a tuned anode circuit transformercoupled to the tuned grid circuit of amplifier 41, the output of which is applied in phase to the control grids of valves 51, 52 via transformer 45, 47 together with an A.C. bias from resistor 50. The anodes of valves 51, 52 are supplied with in phase A.C. voltages from transformer 8, while the screen grids are supplied with out-ofphase voltages derived from oscillator 20 through secondary windings 53, 54, superimposed on an A.C. bias from potentiometer 55, 56. According to the direction of the bridge unbalance voltage the high-frequency components of the screen and control grid voltages are in phase in one valve and in antiphase in the other, making the currents in the two halves of transformer 57 unequal, giving an output in secondary 60 of phase dependent on the phase of the bridge output. This output supplies one winding of a phase-sensitive motor, the connections to which are such that it adjusts condenser 16 to balance the bridge and operates indicator 69 showing the adjustment needed and thus the capacity of 13. Specification 684,761 is referred to.

Abstract: PURPOSE:To make it possible to rapidly complete smoke sensing work without requiring skill, by performing the alteration of an initial set value or a set value only by storing a measured value in a memory means. CONSTITUTION:A smoke sensor is constituted of comparators CP1, CP2 each comparing the output of an amplifier A amplifying the output of a light receiver PD with a set value set so as to emit an alarm at an attenuation ratio (k) to output the output value of said amplifier A only when said output value exceeded the set value, counters CT1, CT2 respectively counting the outputs thereof and a comparator CPM comparing the outputs of the counter CT1, CT2 to emit an alarm. When a set order signal is inputted to an AND gate AN, the output value of the comparator CP1 of which the set value is high at that point of time is inputted to the counter CT1 and set as a comparing reference value. Whereupon, the comparator CPM is set so as to generate output, when the output value NB' always renewed of the counter CT2 became equal to the output value NA (the count value of the counter CT2) of the counter CT1 or the relation of NB<NA is formed, to emit an alarm.

Title: Voice recognition error correcting device
Inventor: ISO KENICHI
IPC: G10L17/06
Filed: 1988-01-06
Abstract: PURPOSE:To practically improve the recognition performance of an acoustic recognizing part by using a reverse propagation network model to correct a time series of symbols including erroneous recognition obtained as the acoustic recognition result. CONSTITUTION:A symbol string as the acoustic recognition result is stored in an input buffer part 1, and an input window part 2 successively segments a fixed-length symbol string from the input buffer part 1 while shirting the start point by every one symbol and inputs it to a reverse propagation network model part 3. The output of this part 3 is stored in an output buffer part 4, and a first control part 5 shifts the start position of the input window part 2 by one symbol to perform the next correcting operation each time when the reverse propagation network model part 3 outputs one symbol. When detecting that correction is performed up to the last symbol in the input buffer part 1, a second control part 6 writes back stored contents of the output buffer part 4 to the input buffer part 1 and performs the correcting operation again, and contents of the output buffer part 4 are started to write in a correction result output part 7 after this process is repeated a fixed number of times. Thus, the recognition performance of the acoustic recognizing part is improved.
